will now be growing freely, and those that are wel] rooted may have. water 
afforded them whenever they become dry. They may also have more air 
whenever the climatic conditions will allow of it with safety. Many of the 
Brazilian Miltonias, as M. spectabilis and its variety Moreliana, M. Bluntii 
Lubbersiana and others will now be developing new roots, and those in need 
of new compost should have attention. It is important, in repotting, that the 
young roots are not injured, as they are very tender and are easily broken. 
They will succeed in the same compost as Oncidiums, and are best grown 
at this season in the Intermediate house. 
AERIDES AND SACCOLABIUMS.—Any plants of these genera, when show- 
ing signs of renewed root action, may have attention as regards repotting 
or resurfacing, should the moss be at all decomposed or in an unsatis- 
factory condition. Aérides succeed grown in pots, while the smaller Sacco- 
Jabiums are more satisfactory in shallow pans, or teak wood baskets, 
suspended from the roof. The receptacles should be well drained, and clean 
live sphagnum moss is the best rooting medium. The moss must be pressed 
into the receptacles moderately firmly, as it is desirable that it should grow, 
and when placed in loosely it often fails to do so. Plants that are not in 
need of repotting may have the old material carefully removed from their 
roots, and the new substituted. Such species as A. odoratum, Lobbii, virens, 
Fieldiugii, Lawrencee#, and Sanderianum, with all the Saccolabiums, will 
be best grown in the Warm house. A. Lindleyanum, A. crispum, A. crassi- 
folium and A. Warneri delight in an intermediate temperature, 
MASDEVALLIAsS that are in need of fresh material at the root, may 
at this season have attention. Any of the stronger growing kinds, 
such as M. Harryana, ignea, and any of the hybrids that did not 
receive attention in the autumn may now be potted, should it be 
requisite. These strong-growing plants are best grown in pots; the 
‘smaller varieties in shallow pans, suspended well up to the light. 
As a rooting medium I use for the strong growers a compost as follows: 
equal parts peat, polypodium and osmunda fibres, and sphagnum moss, 
‘with a fair quantity of half decayed leaves, and half a part of good 
yellow loam fibre. For the smaller growers the latter is left out. M. 
tovarensis, with others ofthe same nature, should be repotted at this season 
just as they commence to grow. They should not be potted too firmly, as 
their roots are not capable of pushing through hard masses of material. 
‘These are best accommodated at the warm end of the Cool house at all 
times. 
CG@LOGYNE CRISTATA and its varieties are now pushing up their flower 
‘spikes and must be afforded sufficient water to keep the pseudobulbs plump 
and the roots healthy, or the flowers will be weak and puny, and their 
flowering will be of short duration. They should not be forced too rapidly
